lNKlNG-FOUNTAIN FOR PRlNTlNG-PRESSES- Specification of Letters Patent.

Patented Nov. 13, 1906;

Application filed January 4, 1906. Serial No. 294,493.

To all whom, it may concern:

Be it known that I, MATTHEW F. DEHLER, a citizen of the United States,and a resident of Syracuse, in the county of Onondaga, in the State ofNew York, have invented new and useful Improvements in Inking-Foun tainsfor Printing-Presses, of which the following, taken in connection withthe accompanying drawings, is a full, clear, and exact description.

The chief object of this invention is to provide simple, inexpensive,and efficient means for quickly and conveniently adjusting theinkgoverning plate (usually termed the knife) to its required positionin relation to the fountain-roll which supplies the proper amount of inkto the printingpress.

In the accompanying drawings, Figures 1 and 2 are elevations of oppositeends of" an ink-fountain embodying my invention. Fig. 3 is a lan view ofthe same. Fig. 4 is a horizonta section taken in a plane immediatelybeneath the ink-governing plate. Fig. 5 is a longitudinal section of thewedge shown in Fig. 4. Fig. 6 is a plan view of the interior of anink-fountain embodying a modification of my invention, and Fig. 7 is atransverse section on the line Y Y in Fig. 6 viewed in the direction ofthe arrow. 3

(it represents the usual plate or knife which governs the supply of inkto the fountain-roll b, which is supported in its position in anysuitable manner and is immaterial to my invention, and therefore merelyindicated by dotted lines. Said plate is connected at its rear edge tothe top of the rear wall 0 of a stationary frame, which is formed with abottom plate (1 and end plates 6 e. The plate a is inclined and has itsfront edge immediately under the ink-receiving fountain-roll b in theusual and wellknown manner and is adjustably supported thereat by meansof the screws f f, engaging at their ends the under side of the plate a,as shown in Figs. 1 and 2.

Prior to my present invention it has been customary to attach the saidscrews to the stationary back wall 0, which was provided withscrewthreaded perforations through which the rear ends of the screwsextended. In consequence of said attachment each of the screws f f hadto be turned, and thus moved longitudinally a proper distance to causeit to sup ort the plate a in its requisite position in re ation t0 thefountain-roll 1).

Such manner of adjusting the said plate is found to be very slow andtedious and annoying to the pressman.

The purpose of my invention is to obviate the said objection, and tothat end I employ a laterally-movable bar g, disposed longitudinally onthe bottom plate d of the frame. To the top of the rear wall a of saidframe is attached the rear edge of the plate (1, preferably by means ofscrews h h, passing through perforations in the plate a and inserted inscrew-threaded sockets h h in the top of the rear wall 0. To the saidmovable bar g I attach the screws ff, so as to cause the entire set ofsaid screws to be moved simultaneously with the movement of the bar.

' Said attachment of the screws is rendered adjustable by providing thebar 9 with screwthreaded perforations through which the screws pass. Therear end portion of each of said screws is smooth and slides freelythrough perforations in the back wall 0.

Various means may be employed for moving the bar 9 laterally toward andfrom the front of the fountain, and I therefore do not limit myselfspecifically to the means shown in the accompanying drawings. I prefer,however, the employment of a longitudinallytapered wedge i, dis osedbetween the back of the bar 9 and the back rest j, which latter isseated stationary on the bottom d and back wall 0, as shown in Fig. 4 ofthe drawings. The said wedge is provided with a longitudinal slot 0',through which the screws f f pass. I preferably ta er the wedge on bothsides and taper the adjacent sides of the bar 9 and back rest j reversefrom the wedge, so as to produce a quick lateral movement of the bar 9 ythe longitudinal movement of the wedge.

The inward movement of the wedge obviously pushes the bar 9 laterallytoward the front of the ink-fountain, and areverse movement of the wedgeallows the bar 9 to move toward the rear of the fountain. To assist thisrearward movement of the bar g, I employ suitable springs Z Z,interposed between the front of the bar and lugs Z P, attached to thebottom plate d.

One end of the wedge '5, preferably the larger end thereof, is providedwith a longitudinal screw-threaded socket n, inwhich is inserted a screw0, journaled in a yoke attached to the exterior of the end wall '6. The

screw is prevented from moving longitudinally by means of collars 0 0,secured to the scrlgw at opposite sides of its bearing in the yo e.

g designates a lever or suitable handle by which to turn the screw 0.

A modification of the means for moving the bar 9 is illustrated in Figs.6 and 7 of the drawings, in which a shaft 1 is used in place of thewedge L. Said shaft is ournaled in the end walls 6 e and has attached toit eccentrics or cams s 8, bearing on the back of the bar 9, which inthis instance is formed with parallel sides. By turning said shaft inone direction the eccentrics or cams s s are caused to force the bar gtoward the front of the fountain, and by a reverse movement of the saidshaft the bar 9 is relieved from the pressure of the eccentrics or camss s, and thus allowed to be moved rearward by force of the springs Z Z.

The screws f f are attached to the bar 9 and move freely in theback-rest j and back wall 0, as hereinbefore described.

What I claim is- 1. In an ink-fountain for printing-presses thecombination with the ink-governing plate, of a laterally-movable bardisposed longitudinally at the rear of said plate, screws attached tosaid bar and bearing on the under side of the plate, and a wedge forcingsaid bar toward the plate as set forth.

2. In an ink-fountain for printing-presses the combination with theink-governing plate, of a laterally-movable bar disposed longitudinallyat the rear of said plate, screws attached to said bar and engaging theunder side of the plate, a longitudinally-movable Wedge forcing the bartoward the plate, and means for moving the wedge as set forth.

3. In a ink-fountain for printing-presses the combination with theink-governing 4. In an ink-fountain for printing-presses the combinationwith the ink-governing plate, of a laterally-movable bar disposedlongitudinally at the rear of said plate, screws attached to said barand engaging the under side of the plate, a longitudinally-movable wedgeengaging the back of the bar and provided, with a screw-threadedlongitudinal socket, and a longitudinally-confined screw j ournaled inthe end of the fountain and inserted in the aforesaid socket as setforth.

5. In an ink-fountain for printing-presses the combination with theink-governing plate, of a laterally-movable bar disposed longitudinallyat the rear of said plate and provided with transverse screw-threadedperforations and with a longitudinally-tapering back, a stationary backrest tapered reverse from the taper of the aforesaid bar, a wedgeinterposed longitudinally between said bar and back rest and providedwith a longitudinal slot and with a screw-threaded socket in its end, ayoke attached to the end of the fountain, a longitudinally confinedscrew journaled in said yoke and inserted in the aforesaid socket,springs holding the movable bar in contact with the wedge, screwspassing transversely through the said bar and slot of the wedge andsupporting the aforesaid plate as set forth.
